GridView dynamic column width in WPF

Question

<Window x:Class="GridViewSample.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" > <Grid> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <ListView Name="CheckoutList" Margin="0,0,8,0"> <ListView.View> <GridView x:Name="CheckOutGridView"> <GridView.ColumnHeaderContainerStyle> <Style TargetType="{x:Type GridViewColumnHeader}"> <Setter Property="Visibility" Value="Collapsed"/> </Style> </GridView.ColumnHeaderContainerStyle> <GridViewColumn> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock> <Hyperlink > <TextBlock Text="{Binding Path=Text}"/> </Hyperlink> </TextBlock> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock> <Hyperlink> <TextBlock Text="Remove"/> </Hyperlink> </TextBlock> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> <StackPanel Grid.Row="1"> <Button Width="100" Height="25" Click="Button_Click" >name</Button> <Button Width="100" Height="25" Click="Button_Click1" >long name</Button> </StackPanel> </Grid> 

 public partial class Window1 : Window { class TextObject { private string _text; public TextObject(string Text) { _text = Text; } public string Text { get { return _text; } set { _text = value; } } } public Window1() { InitializeComponent(); } private void Button_Click(object sender, RoutedEventArgs e) { CheckoutList.Items.Add(new TextObject("name")); } private void Button_Click1(object sender, RoutedEventArgs e) { CheckoutList.Items.Add(new TextObject("long name")); } } 

Given the above example, click the name and then the long name. Why don't the columns change according to its contents?

Answer 1

Try

 <GridViewColumn Width="{x:Static System:Double.NaN}"> 

Where

 xmlns:System="clr-namespace:System;assembly=mscorlib" 

and this should help you resize the column to fit the contents of the header.
